This invention relates to means for supporting superheater pipes-within the flues of boilers and has for its primary object the clamping together of the pipes whereby the pipes are held out of contact and rigidly in respect one to the other and are held away from the flue surface so that there may be no grinding action as would otherwise occur should cinders work between the pipes and the pipes be permitted to work or vibrate one over the other. Other objects reside in the supplying of such means in an extremely simple form lending itself to quantity production at a very low cost, and in the ease and rapidity of installing such means.

The invention is described in the one par ticular form now best known to us as shown in the accompanying drawing, in which-- Fig. 1 is a fragmentary side elevation of a short length of boiler flue showing the invention applied therein;

Fig. 2, a vertical transverse section on the line 22 in Fig. 1;

Fig. 3, a side elevation of the upper half of the bracket; and

Fig. 1, a top plan view of the lower half of the bracket. 7

Like characters of reference indicate like parts throughout the several views of the drawings.

The bracket is made in two parts, the upper part being generally designated by the numeral 10 and the lower part by the numeral 11. The lower part 11 of the bracket is preferably made of steel about one-eighth of an inch in thickness and is formed to have a central upper portion 12 curved outwardly from thevertical axis from whence the material is curved back inwardly and downwardly from each side of the portion 12 to contact one side against the other, and each side then is curved outwardly downwardly and around to conform to the circumference of the superheater pipes 13' and 14 to slightly beyond the Vertical center lines of the pipes 13 and 14:, from which points the material is dropped sharply downward at approximately degree angles to form the legs 15 and 16. Slots 17 and 18 (Fig. 4) are cut respectively at the lines on which the legs 15 and 16 are turned down,

The upper partlO of the bracket is preferably formed of sheet steel approximately one-sixteenth of an inch thick and is preformed'to fit snugly around thetwo pipes-13 and'lt as the} are carried on the bracketpart 11, Fig; 2, with the legs'l9 and 20 extending vertically downwardly as indicated bythe dash lines so that these-legs 19 and 20'may lie-extended through the slots 17 and 18 in the lowe'r part 11, and the legsthen bent over and upwardly against the under sides of the legslo and 16.-The legs 15 and 16 rest'against the flue 21. 1 5

The curved upper end 12 of the lower part 11 prevents the pipes 13 and 1 1 from jumping upwardly, since, to rise upwardly, the pipes 13 and 14 'wouldhave to move horizontally first to clear the portion 12,- but the bracket part 10 prevents such lateraltravel. The upper bracket part lOis here shown with the legs "19'and QOreduced slightly in width'from the width of the bracket, Figs. 1 and 3, to form a shoulder to each side to act as stops limiting the extension ofthe legs 19 and 20 through the slots 17 and 18, the slots being just -longenough to permit the legs to slide therethrough freely. While wehave heredescribed our invention in one particular form, it is obvious that structural changes may-be made without departing'from the spirit of the invention, and we therefore do not desire to be limited to the precise form as shown and'described, nor any more than may be requiredby the following claims.

We claim:

1. A pipe bracket for maintaining pipes in spaced alinement comprising apiece of sheet metal formed to have a shoulder conforming to the curvature of the pipes, the metal being carried from the shoulder around and upwardly between one pipe and the next adjacentpipe and thence bent around back against itself to return between the same two pipes forming a separator between the pipes and to continue around under the second pipe to form a shoulder thereunder, both shoulders .of the bracket terminating close to vertical planes through the centers of their respective pipes, said separator having a greater thickness above than at a plane through the center lines of the pipes, and legs extending from the shoulders having slots at their junctions with the shoulders.

2. A pipe bracket for maintaining pipesin spaced alinement comprising a piece of sheet metal formed to have a shoulder conforming to the curvature of the pipes, the metal being carried from the shoulder around and upwardly between one pipe and the next adjal cent pipe and thence bent around back against itself to return between thesame two pipes forming a separator between thepipe's and to continue around under the second pipe to form a shoulder thereunder, both shoulders of the bracket terminating close to vertical planes through the centers of their respective pipes, said separator having a greater thickness above than at a plane through the Center lines of the pipes, legs extending from the shoulders having slots at their junctions with the shoulders, and a sheet metal clamp shaped to pass around the pipes on the sides removed from the shoulders, said clamp having legs adapted to pass through the slots in the legs and to be bent against the under side of the legs.

3. A pipe bracket for maintaining pipes in spaced alineinent comprising a piece of sheet metal formed to have a shoulder conforming to the curvature of the pipes, the metal being carried from the shoulder around and up- 1 wardly between one pipe and the next adjacent pipe and thence bent around back against itself to return between the same two pipes forming a separator between the pipes and to continue around under the second 5 pipe to form a shoulder thereunder, both shoulders of the bracket terminating close to vertical planes through the centers of the respective pipes, said separator having a greater thickness above than at the plane through the centers of the pipes, legs extending from the shoulders, and means for retaining the pipes on the shoulders.

In testimony whereof we affix our signatures.
